Time Reversal

Time reversal may refer to:

  • In physics, T-symmetry - the study of thermodynamics and the symmetry of certain physical laws where the concept of time is reversed — i.e. where a mirror (reverse) transformation is applied to a forward direction time state.
  • Time Reversal Signal Processing, a signal processing technique popular in acoustics, and currently being applied to electromagnetics, that results from the reversal in time of a system's response signal
  • Time travel, theorised and speculative concepts about travelling physically through time

Famous quotes containing the words time and/or reversal:

    “Literature exists at the same time in the modes of error and truth; it both betrays and obeys its own mode of being.”
    —Paul Deman (1919–1983)

    “Perversity depends on reversal and substitution.”
    —Mason Cooley (b. 1927)
